Administration of the MapR-DB is done primarily via the commmand line (maprcli) or with the MapR Control System (MCS).
Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are used
with slightly different parameter options. MapR-DB administration is associated with tables, columns and column families,
and table regions.

Permissions Required at the Source Cluster

Note: The mapr user is not treated as a
superuser. MapR Streams does not allow the mapr user to run this command
unless that user is given the relevant permission or permissions with access-control
expressions.

Permissions Required at the Target Cluster

To run
this command, your user ID must have the following permissions:

Parameters

The path and name of the stream that you want to create a replica for.

replica

The path and name of the stream that you want to create as a replica of the
stream that you specified with the -path parameter.

newreplica

Specifies a new name to give to the replica stream.

throttle

A boolean value that specifies whether to throttle replication operations.
Throttle the replication stream to minimize the impact of the replication process on
incoming operations during periods of heavy load. The values are
true or false. The default is
false.

Throttling has two effects, both of which allow MapR Streams to
use more system resources to process new messages:

Throttling slows down the rate at which changes to a stream are
replicated.

Throttling slows down the rate at which messages to be replicated are read
from disk.

networkencryption

A boolean value that specifies whether or not to enable on-wire encryption. The
values are true or false. The default is
false. If you set the value to true, the local
cluster and any other cluster that is part of the replication process must be
enabled for security.

synchronous

A boolean value that specifies whether replication is synchronous or
asynchronous. The values are true or false. The
default is false and specifies asynchronous replication.

networkcompression

Specifies the type of compression to use when replicating messages. For more
information, see Compression.
